To all whom t may concern.'

Be it lrnoxvn that I, DAN GRIFFITH, a citizen of the United States, and a resident ot Tacoma, in the county oit Pierce and State of ldlashington, have invented certain new and useful Improvements in Heating- Devices, of which the following is a speciiication.

My invention is an improvement in hea ing,I devices, and has for its obje/et to provide apparatus for use in connection with stoves and the like` for permitting a large amount of the heat usually wasted to be utilized, to heat the room in which the tireis arranged, or to heat other rooms.

In the drawings:

Figure l is a sectional vievv showing the device arranged to heat another room;

Figure Q is a section on the line Lil-lief Figure l.

In the embodiment of the invention shown in Figures l. and 2, the device is shown in connection with a heating stove lf3 which has a draft pipe Ll opening` into the flue l5. The drum comprises a casing, 1G which is arranged Within another room, as shown, and this casing has inlet and outlet pipes 17 and i8 which connect the casing with the ilue, the inlet pipe being at the bottom of the casing` While the outlet pipe I8 is at the top.

A baille plate 19 is arranged transversely of the easing, the battle plate at its 'front edge being spaced apart from the trent wall o't the casing` to provide a passage for the heated as shown. and the casingis provided With a door opening 2O below the baille plate, normally closed by a door 2l. This door opening permits the casing to be cleaned when necessary.

A damper 22 is slidably mounted in the pipe 'i7 to be moved across the flue or to be moved into the pipe 17 Where it will not in. tertere with the passage through the flue, a rod 23 being` connected with the damper and having a jointed section 2i at the end remote from 'the damper.

The rod is slidable through an opening in the easing, and it will be obvious that when the jointed section 24 drops down outside of the casing, indicated in dotted lines in Figure 3, the damper will be held in the pipe 17. The damper moves in guides 25 in the pipe. lVith this arrangement, when it is desired to heat the room in which the casing 16 is arranged.,'the hinged portion 24- oi the rod is lifted and the damper is pushed inwardly into position across the iue.

The heated gases now pass `trom the stove through the draft pipe I4, the flue and the pipe 17 into the Casing lr6. Il rom here they pass througl'i the pipe 18 and again into the iiuey rlhe casing` I6 Will be heated, thus utilizing the heat which is generally Wasted.

I claim: I

i heater'as herein set Yforth comprising a easing including iront and rear Walls, said rear Wall provided with openings and upper and lower pipes adapted for connection with a vertical lille, an intermediate baii'le plate within the casing` extending trom the rear wall to near the tront wall, guides arranged within the lower pipe within its upper Wall, a damper pl are ot somewhat greater length than the width ot the vertical 'Hue slidable in said `guides. and a jointed handle attached to the front ol said damper plate and eX- ten ding through the iront wall ot the casing.
